I saw a story on this town on the H Channel's Engineering Disasters. Since then I cannot stop thinking about it. There is something that intrigues me about abandoned towns, dying cities and the decay of where people once "mastered". Not do much the cause of their demise, but the decline itself and deterioration itself.

I looked it up on Google Earth, and it is just as the wiki article describes. There are only a few buildings dotting otherwise empty blocks. The highway is.....abandoned, I mean it just seems like it would be a crazy place to go check out.
